UC Chances?

<p>Hello, all! I am going to be a senior this year, Class of 2013, and I'm really freaking out about college apps.
During second semester of my sophomore year, I went through a bit of a rough patch.
I had a falling out with my parents, and was irrational about it. (Not trying in school, ditching, falling in with the wrong crowd, etc.) To make matters worse, my uncle, whom I was very close to died. My parents decided to transfer me to another school, but it was too late. There was a stain on my transcripts. I realized too late that I was an idiot and should have listened to my parents. Fortunately, my grades showed a slight upward trend at this new school, but not a great one. I developed a lot of bad habits my during sophomore year, and I'm recovering. My AP Statistics teacher this year really gave me some motivation to do better. She brought some sense into me by calling me out on a lot of the negative things about me. This senior year, I'm willing to throw away my social life and concentrate on school, something I have not done for a while. Now, I'm freaking out about college and feeling very guilty for not listening to my parents.</p>

<p>GPA: 3.44 unweighted
SAT: 1820 (Going to take another one in October and SAT IIs in November)
AP courses:

<p>I want to major in Philosophy and/or Statistics, but keep playing my horn.
What are my chances at UCSB, UCD, UCSC, or UCSD?</p>
